Athletico Paraense chief Luiz Felipe Scolari says Vitor Roque is set to be sold.
The teen is a top target for Arsenal and Barcelona.
Former Brazil boss Scolari said: Vitor will probably be sold.
He's 17 years old and has a lot to learn on the pitch. But he's been playing in the Campeonato Brasileiro and the Copa Libertadores since he was 16.
"He's a 17-year-old boy with the brain and experience of a 24 or 25-year-old.
He's ready. When (a club) comes up with enough money, I think we will sell."
